I need some useful advice...I have a S-14 Lund with a 20" transom. I have a great running 25hp tiller Evinrude that I don't want to part with. The shaft length is 18"...Too short for the boat...If I buy a 5" extension for the motor it will be a few inches too long. Should I extend the shaft or has anyone lowered a tiller steer outboard a few inches with a transom bracket. I will not cut my transom down. I am not crazy about extending the shaft AND buying a jack plate to raise it back up.
